A letter box is seen outside the headquarters of Germany's second largest business bank, Commerzbank AG in Frankfurt, December 3, 2013. German prosecutors searched Commerzbank offices on Tuesday, looking for evidence that a foreign life insurance company may have helped German investors evade taxes. State prosecutors in Bochum said around 270 tax officials participated in the raids across Germany, probing the sale of wealth management products disguised as life insurance.
